Abstract

We introduced and realized with our MuVarch approach an heterogeneous (meta)modeling environment for multi-view representation of heterogeneous embedded architectures (of "smartphone" type for instance). In addition to the backbone architectural view supporting others, we considered performance, power, and thermal view. We introduced also the functional applicative view, to provide typical use cases for the architecture. It was important to describe in MuVarch our various views would connect to the basic one, and how they would mutually relate together as well (how temperature depends on power consumption for instance). The global objective was to let the framework consider alternative mapping/allocation strategies for applicative tasks on architectural resources (although the definition of such strategies themselves was out of the scope). The appropriate form of such an allocation relation, which may be quite involved, was thus an important aspect of this thesis.
